How to Get an ADHD Assessment for Your Child in the UK - 2026 Guide

To get an ADHD assessment for your child in the UK, the first step is a GP appointment. You explain your concerns, ask for a referral, and from there you enter either the NHS pathway through CAMHS or a community paediatric team, or the NHS Right to Choose route via an independent provider. In 2026, NHS waiting times for children range from around one to four years in most parts of England, though this varies significantly by region. Private assessment is available within weeks but costs between 500 and 1,500 pounds. A formal diagnosis, however, is not a requirement for support. Schools can make adjustments based on observed need, and a parenting coach can help you develop strategies right now. This guide explains the full process step by step, what to say to your GP, what the assessment involves, and critically, what you can do for your child while you wait.

Introduction: Why Getting an ADHD Assessment Feels So Hard

If you have been watching your child struggle and wondering whether ADHD might explain some of what you are seeing, you are not alone. Referrals for children's ADHD assessments have surged across the UK in recent years, and the gap between demand and NHS capacity has never been wider.

For many families, the process feels bewildering. You might have left a GP appointment feeling dismissed, waited months only to be told the list is even longer than expected, or found conflicting information online about private assessment and what it actually means for your child's support at school.

Bakshi Sidhu is a certified conscious parenting coach, former primary school teacher of ten years, and nursery owner of five years. She has supported many families through the ADHD assessment journey, from the first GP conversation to what comes after a diagnosis. This guide is designed to give you a clear, honest picture of the process in 2026 so that you can move forward with confidence rather than frustration.

Step One: Talking to Your GP About ADHD Concerns

How to prepare for a GP appointment about ADHD

The GP appointment is where everything starts, and how you prepare for it matters more than most parents realise. A GP sees a child for ten minutes in a clinical environment. That is not enough time or context for them to observe the behaviours you are concerned about. Your job is to bring that context to them.

Before the appointment, write down:

- Specific examples of behaviours you observe at home, including how often they happen and how long they have been going on

- Any feedback you have received from nursery, childminders, or school staff

- How the difficulties are affecting your child's daily life, friendships, learning, or emotional wellbeing

- Whether symptoms are present in more than one setting, which NICE guidance identifies as a key diagnostic criterion

Bring this written summary to the appointment. It gives the GP concrete information to work with and makes it much harder for concerns to be brushed aside as a phase or normal behaviour.

What to say if your GP is reluctant to refer

Some GPs are hesitant to refer for ADHD assessment, either because of awareness of waiting lists, or because the child presents as calm and compliant in the consultation room. If you encounter resistance, you can calmly reference NICE guideline NG87, which sets out that children with significant ADHD-related difficulties in more than one setting should be referred for a specialist assessment. You do not need to be confrontational. You can simply say: 'I understand waiting lists are long, but based on what I am observing at home and what school has reported, I would like a formal referral please.'

If your GP declines, ask for their reasoning in writing. You have the right to seek a second opinion from another GP at the same practice, or to register with a different surgery.

What Happens After a GP Referral for Child ADHD Assessment?

Once a referral is made, it will be sent to one of two places depending on your area: your local Child and Adolescent Mental Health Service (CAMHS), or a community paediatric team. Both can carry out ADHD assessments, though the waiting times, process, and communication style vary.

You should receive an acknowledgement of the referral, followed eventually by an appointment letter. In some areas this acknowledgement alone can take several months. If you have not heard anything after six to eight weeks, it is reasonable to contact the service directly and ask for confirmation that your referral has been received and what position you are on the waiting list.

Under NHS guidelines, you are entitled to ask for updates on your waiting list position. Some services provide these proactively. Others require you to ask. Do not assume silence means the referral is lost - but do follow up if you have heard nothing within two months.

NHS Waiting Times for Child ADHD Assessment in 2026

The honest picture is difficult to read. In 2026, NHS waiting times for children's ADHD assessments in England range from around twelve months in the fastest areas to over three years in many others. Some areas are longer still. This is not a reflection of the quality of care available once you reach assessment. It is a capacity crisis that has been building for over a decade as referrals have grown far faster than services.

Families in different parts of England face very different realities. A child referred in one London borough might be seen in eighteen months. A child referred in certain parts of the Midlands or North West might wait three to four years. There is currently no national standard waiting time target specifically for children's neurodevelopmental assessments, though NHS England has acknowledged the problem.

Knowing the likely wait in your area before you start the process helps you plan realistically. Your GP, your local Integrated Care Board (ICB) website, or patient groups such as ADHD UK can often give you a rough indication of current local waiting times.

What Is NHS Right to Choose and Does It Apply to Children?

NHS Right to Choose is a policy introduced in England in 2018 that allows patients to request a referral to any eligible provider offering NHS-funded care, including some independent and private clinics, rather than being limited to their local NHS service.

For adults, Right to Choose for ADHD assessment is relatively well established. For children, the picture is more complicated. The application of Right to Choose to children's ADHD assessments varies by Integrated Care Board. Some ICBs have embraced it, which means a GP can refer your child to an independent clinic that offers a shorter waiting time while remaining fully NHS-funded. Others have not, or have placed restrictions on how it applies.

The key question to ask your GP is: 'Is NHS Right to Choose available for children's ADHD assessments in this ICB?' If the answer is yes, ask which independent providers are currently accepting Right to Choose referrals. Typical waiting times via this route in 2026 range from around six to eighteen months, though this is also lengthening as more families use the scheme.

Should You Consider a Private ADHD Assessment for Your Child?

The case for going private

Private ADHD assessment is the fastest route to a diagnosis. Most private clinics in the UK can offer appointments within two to eight weeks. For a child who is struggling significantly at school or at home, waiting one to four years for an NHS assessment has real costs: to their academic confidence, to their friendships, to their sense of self, and to your family's daily life.

A private diagnosis is clinically valid and should be accepted by your child's school, GP, and any other professional involved in their care. Many GPs will enter into a shared care arrangement following a private diagnosis, meaning ongoing prescribing and monitoring is handled by the NHS rather than at private cost.

What does a private ADHD assessment for a child cost in 2026?

Private child ADHD assessments in the UK typically cost between 500 and 1,500 pounds. The variation reflects differences in what the assessment includes, the seniority of the clinician, the clinic's location, and whether the fee covers a follow-up appointment and written report.

Before booking, ask the clinic:

- Whether the assessment includes a comprehensive written report suitable for sharing with school and GP

- Whether the fee includes a follow-up appointment to discuss the outcome

- Whether they have experience of shared care arrangements with NHS GPs in your area

- Whether they are registered with the Care Quality Commission (CQC), which all private healthcare providers operating in England must be

A word on online-only assessments

The growth of online ADHD assessment services has expanded access significantly, but quality varies. Some online providers offer thorough, clinically robust assessments conducted by qualified psychiatrists or paediatricians. Others are less rigorous. Before booking any online assessment, check that the provider is CQC-registered, that the assessing clinician holds appropriate UK clinical qualifications, and that the resulting report will be accepted by your child's school.

What Does a Child ADHD Assessment Actually Involve?

Whether the assessment is NHS or private, the process tends to follow a similar structure. Understanding what to expect helps you and your child prepare.

A thorough ADHD assessment for a child will typically include:

- A detailed clinical interview with parents or carers covering the child's developmental history, current difficulties, and family background

- Standardised behaviour rating scales completed by parents and, where possible, by school staff

- Direct observation of or interaction with the child

- A review of school reports, previous assessments, or any relevant educational records

- Sometimes a cognitive assessment or computerised attention test such as QbTest, which NICE guidance added as an option in 2024

The clinician will be looking for whether ADHD symptoms are present across more than one setting, whether they began before the age of twelve, how long they have been present, and whether they are causing significant impairment in daily life. NICE guidance is clear that a diagnosis should not be made solely on rating scales or observational data alone - a full clinical picture is required.

The outcome will be either a formal diagnosis, a conclusion that another condition better explains the difficulties, or a recommendation for further assessment. Whatever the outcome, a good clinician will explain their reasoning clearly and outline next steps.

What Can You Do for Your Child Right Now, Before the Assessment?

This is the question that matters most for many parents, and the answer is more than you might think. A formal diagnosis is not the starting gun for support. It is one step on a longer journey that you can begin walking today.

At home

Understanding how ADHD affects your specific child's nervous system, emotional regulation, and sensory experience allows you to respond more effectively to their behaviour and reduce daily conflict. Many of the strategies that help ADHD children also benefit all children: clear routines, short instructions, movement breaks, and connection before correction.

At school

Schools in England have a legal duty under the Equality Act 2010 to make reasonable adjustments for children with disabilities, and ADHD can constitute a disability under this act. A diagnosis is not required for reasonable adjustments to be made. You can speak to your child's class teacher or the school SENCO right now and ask what can be put in place based on observed need.

Useful adjustments schools commonly make include: preferential seating, movement breaks, use of fidget tools, chunked instructions, and regular check-ins.

Working with a parenting coach

One of the most impactful things parents can do while waiting for assessment is work with a parenting coach who understands ADHD. This is not the same as therapy for your child. It is support for you, as the adult who is navigating the system, managing daily behaviour, and trying to stay regulated yourself when things are hard.

NICE guideline NG87 explicitly recommends that group-based ADHD-focused parenting support should be offered before formal diagnosis where possible. A conscious parenting coach who specialises in ADHD can offer this kind of structured, personalised support.

Understanding the Difference Between ADHD Assessment Routes

NHS standard pathway vs Right to Choose vs private

Here is a straightforward comparison to help you decide which route makes most sense for your family right now.

- NHS standard pathway: Free. Referral via GP to CAMHS or community paediatrician. Waiting time typically one to four years in 2026. No upfront cost but significant delay.

- NHS Right to Choose: Free. Referral via GP to an approved independent provider. Available in some ICBs for children. Waiting time typically six to eighteen months currently, though growing. No cost if available in your area.

- Private assessment: Cost of 500 to 1,500 pounds. Available within weeks. Diagnosis accepted by schools and GPs. Shared care prescribing usually available. Best option if immediate support is critical.

The right choice depends on your child's level of current difficulty, your financial situation, and what is available in your area. Many families begin the NHS referral process immediately while also exploring Right to Choose, so they are on multiple lists at once.

After the Assessment: What Happens Next?

If your child receives an ADHD diagnosis, the assessment report becomes a key document. Share it with:

- Your child's school SENCO, who can use it to develop or update a support plan

- Your GP, who can discuss medication options if appropriate and enter into a shared care arrangement with any private prescriber

- Any other professionals involved in your child's care, such as an occupational therapist or speech and language therapist

If medication is recommended and you are unsure about it, take your time. Medication is one part of a broader support picture, not the only option and not always the right starting point for every child. Your parenting coach, GP, and the assessing clinician can all help you think through what makes sense.

If the assessment concludes that ADHD is not the primary explanation for your child's difficulties, that is also valuable information. Other conditions such as anxiety, sensory processing differences, autism, or learning difficulties may better explain what you are seeing, and a good assessor will outline what further investigation or support might help.

ADHD Assessment for Girls and Children Whose Symptoms Are Less Obvious

It is worth addressing this directly because it affects a significant number of families. ADHD in girls has historically been under-diagnosed. The hyperactive and impulsive presentations most commonly associated with ADHD in popular understanding are more typical in boys. Girls more often present with inattentive ADHD: daydreaming, difficulty organising themselves, forgetfulness, and emotional sensitivity. These presentations are frequently missed or attributed to personality rather than neurodivergence.

Similarly, children who are academically bright, or who have learned to mask their difficulties in school, may not present as obviously struggling. A child can be exhausted by the effort of holding themselves together all day and completely dysregulated at home, with school reporting nothing concerning.

If you feel your child's difficulties are being dismissed because they do not fit the stereotypical ADHD picture, persist. Bring detailed evidence. Ask specifically about inattentive ADHD presentation. And consider seeking a clinician with particular experience of ADHD in girls or in children who mask.

Conclusion: Start the Process Today, and Get Support While You Wait

The ADHD assessment process in the UK in 2026 is genuinely difficult. The waiting times are real, the system is stretched, and the experience of navigating it while also managing a child who is struggling can be exhausting and demoralising.

But here is what Bakshi wants every parent reading this to know: the assessment is not the beginning of support. Your child can be helped right now. You can make changes at home, ask for adjustments at school, and work with a parenting coach to feel more grounded and effective in how you respond to your child's needs today, not in two years when the appointment finally arrives.

Start the GP referral process. Explore Right to Choose. Consider private assessment if the wait is unworkable. And in the meantime, do not wait for a piece of paper to start showing up for your child in the ways that will make the biggest difference.
